The README should be enough to put you in the right direction. The one weird thing I had to do to get my stylesheet on the server is to manually parse webpack stats:
const chunks = JSON.parse(fs.readFileSync('./dist/assets/webpack-chunks.json', 'utf8'))
const style = chunks['styles']['main']
// And then where I'm rendering my server markup:
{style && <link rel='stylesheet' href={style} />}
I'm also using webpack v1 so things have probably changed quite a lot. I recommend you try to find a good boilerplate or tutorial to follow that handles server-side rendering with CSS Modules.

Server side rendering is a large problem of its own to solve, but essentially you need to use universal-webpack and extract-text-webpack-plugin to extract out your CSS and
<link />to it in your server. I remember the major issue that I had was not being able to get Node to recognize myimport style from './index.css'statements, but I think universal-webpack solved that for me. I also recommend you check out Next.js.
